“…Clay minerals, in particular montmorillonite, are also important for soil remediation, as pollutants can be adsorbed on their surface and/or intercalated in the interlayer [8][9][10][11]. The remediation process involves the fundamental role of water as a solvent and is usually controlled by the cation exchange capacity (CEC) of montmorillonite, which can be affected by the surface charge of the 2:1 layers [12][13][14].…”

“…The immobilization of heavy metals in soils has been a hot research topic for a long time. [172][173][174][175][176] It is recommended to explore the application potential of halloysite-based nanotubular adsorbents (e.g., decorated with chelating agents in the lumen) in the immobilization of soil heavy metals. To this purpose, it is necessary to examine whether this nano-tubular adsorbent can confine heavy metals in the lumen and consequently reduce their mobility and bioavailability in soil environments.…”

“…Numerous amendments have been investigated to effectively immobilize Cd in soils, such as biochar, zeolite, and clay minerals (Usman et al, 2006;Khan et al, 2017;Zhu et al, 2017). Clay minerals are one of the most abundant substances on the earth, and the feasibility of clay minerals as an amendment to immobilize heavy metal-contaminated soil has been intensively studied (Qin et al, 2020). For example, Sun et al (2016) showed that sepiolite was effective in immobilizing Cd and reducing Cd toxicity, thus improving the environmental quality of soils.…”
